[OAnderson]

Mercedes-Benz car cannot shift into reverse gear reasons introduction: Fault inside the gear lever assembly: The internal gears of the gear lever are worn, causing the gear lever to jam, making it very difficult to pull forward and backward. Faulty brake switch: The P-gear locking solenoid valve inside the gear lever has malfunctioned, or the brake switch is faulty. Incomplete clutch separation: This may be caused by the failure of the clutch disc and clutch pressure plate, which generally requires replacement of the clutch three-piece set. Battery leakage: Insufficient power prevents startup. If the engine cannot start, check if the battery power is insufficient. Then inspect the starting system. First, check the circuits in the engine starting system. From the most basic composition, the starting system circuit generally includes the following basic parts: the battery, the starter motor, and the cables connecting these components.
